Roxanne purchased a necklace from New York Jewelry (NYJ) on a layaway plan under which NYJ would keep possession of the necklace until she had paid for it in full.Roxanne and NYJ entered into an oral security agreement in connection with the layaway plan.About six months later, Roxanne went into Chapter 7 bankruptcy and listed NYJ as one of her creditors.When the bankruptcy trustee notified NYJ to come to a meeting of the creditors, NYJ responded by saying that since it had a security interest in the necklace, this was a secured debt that would not be part of a bankruptcy proceeding.The trustee responded to that position by stating that NYJ did not have a valid security interest in the necklace and as result this was an unsecured debt which would be part of the bankruptcy proceeding.Who is right and why?
